SPRING MATTRESS AND LIKE S'Ilflftl'GEITU'LRE.v

Application filed .Tune 7,

The invention relates more particularly to that class of mattresses and cushions in which a series of coil springs are employed, the object of the invention being to provide improved means for holding the coil springs in proper relative position within the outer easing 0r sheath whereby the springs are inclosed. The invention consists in the novel features hereinafter described, illustrated in the accompanying drawings and particularly pointed out in the claim at the end of this specication.

Figure 1 is a view in vertical section through a portion of a spring mattress or cushion embodying my invention. `Figure 2 is a plan view. Figure 3 is a detail view in vertical section on line 3-3 oi- Fig. 1. Figure 4 is a perspective view showing a suit` able form of staple used for connecting certain parts.

The casing A that incloses the coil springs B will be of ticking or other suitable mat-erial and is shown surrounded by a pad or cushion C having a covering c, the pad C being connected to the casing A by tutting cords D, in manner well understood by those familiar with this class of devices. The coil springs B are arranged in rows as shown in Fig. 2 of the drawing, and the top and bottom terminal coils b of the springs B bear against the top and bottom walls a and a of the casing A. Under the terminal coils b of the springs B extend strips of textile material, these strips being preferably formed of heavy tape or webbing E and E that cross each other at right angles, as clearly shown in Fig. 2 ot the drawing. At points between the terminal coils of adjacent springs B the strips of webbing E and E are securely fastened to the adjacent walls a and a of the casing A, preferably by means of staples F. Thus, by reference to Figs. 1 and 3 of the drawing, it will be seen that the top strips of webbing E are secured to the upper wall a of the casing A by the staples F, while the bottom strips of webbingE are similarly attached to the bottom walls a of the casing, the staples F in each instance uniting the strips of webbing E to the walls of the casing at points between the terminal coils b of adjacent springs B. In like manner, the strips of webbing E will be united to the top and bottom walls of the casing A by the staples F, the staples F uniting the strips of webbing E to the casing being arranged at 1924. Serial No. 718,443.

right angles to the staples that serve to conneet the strips of webbing E to the casing;

`When the strips of webbing E and E are united to the casing walls as last described, they serve to form with these walls pockets for receiving and holding in place the terminal coils b of the springs B. To enable the terminal coils of the springs B to be inserted in their proper places between the strips of webbing E and E. and the walls a and a of the casing A, the terminal coils of the springs B will be slightly compressed so as to reduce their diameter, and also will be rotated slightly so as to permit their terminal coils b to be slipped between the broad strips oi2 webbing E andE and the walls a and a adjacent these strips of webbing and when the terminal coils have been inserted between the strips of webbing and the walls ofthe casing, the tension on the coils will be released and they will be permitted to assume the position use, they will be securely retained against danger of acci-dental displacement and as well also against danger of Contact with each other.

Since the specific embodiment herein disclosed is merely illustrative of a single application of my invention, it will be understood that the scope of same should be deter mined by reference to the appended claim, said claim being construed as broadly as possible, consistent with the state of the art.`

Having thus described my invention, what I claim as new and 'desire `to secure by Let` ters Patent is v ln a mattress or like structure, the combination of a mattress tick including top and bottom walls, a plurality of spiral coil springs arranged within said tick so as to form two sets ot' parallel rows of springs, the rows ot' one set extending transversely of the rows of the other, and at substantially right angles thereto, each of the springs `being common to two relatively transversely extending rows and having their top and bottom end coils respectively disposed against the top and bottom tick walls, and means for maintaining the springs so arranged comprising a tape strip for each of said rows of springs, eX- tending longitudinally thereof, inside and substantially diametrically of the end coils of the springs in the row, the strips for two relatively transversely extending rows intersectng euch other substantially axially of the spring common to the two rows und beingr fastened to the adjacent tick Wall at points adjacent the outer perpheries of the end coils of such common .springs, thereby forming with said'tick W111i, pockets for receiving the end coils and preventing contacting of the end coils of adjacent springs, the fastening of said strips to the tick wall being relatively Short orosswise of the strip so as to provide alelatvely wide space between the adjacent i'astenings around each pocket, thereby per Inittng said end coils to be inserted into the pockets after the strips are fastened to the tiek wells.
